Constant Current PWM v2.1H Populated PCB HHO Hydrogen

Zero Fossil Fuel PWM v2.1H Printed Circuit Board - Fully Populated

If you are building a PWM, this is a must!! Save yourself HOURStracking down all the different components and soldering them on a Prototype board. It fits perfectly inside the G106 enclosure. Components may vary slightly from the ones pictured as these are hand built.

This listing is for the PCB and components soldered on the board. It does not include a mosfet, case, diode, C5/C7, or documentation. Schematics are available at alt-nrg.org. I will try to answer any questions you may have, but cannot offer “tech support” for the finished product.

All orders are shipped USPS First Class with delivery confirmation.

International orders – please contact me FIRST before bidding.
